' ROLLER-BEARING.

Specication of Letters Patent'. Application filed December 5, 1908. Serial No. 466,049.

Patented Sept. 7, 1909.

To altfwhom 'it may concern:

Beit known that I', ONESIME E. MICHAUD, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a newl ,and useful Improvement in RollerBearings, of which the following is a specification.

This invention relatesto roller bearings. It has for its principal objects to simplify the construction, facilitate the manufacture and minimize the cost of spacing frames or cages for the rollers; to facilitate the ready assenbling and removal of the rollers; and to altain certain other advantages hereinafter more fully appearing.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanyin drawing, which forms part of this speci cation and wherein like symbols refer to like parts wherever they occur, Figure 1 is an end elevation of a circular spaclng frame or cage embodying my invention wlth the rollers in position thereon; Fig. 2 is a cross section through the outer end portion of an axle and a roller bearing thereon embodying my invention; Fig. 3 is a longitudinal Vsection of the arrangement shown in Fig. 2; Fig. 4 is an edge View of a spacing frame or cage embodying ,v my invention with the rollers removed; Fig.

5 is a longitudinal section of a modification of the spacing frame or cage; Fig. 6 is a flat face view of 'a perforated strip or blank for a further modification of the spacing frame or cage; and, Fig. 7 is partly an edge View and partly a longitudinal section of ille blank as indicated by the line 7-7 of In the drawings, the' end port-ion 1 of an ordinary vehicle/aXl/e is'shown. On the axle is sleeved a bearing ring or sleeve 2. Preferably the ring or sleeve 2 is provided with a screw threaded nut portion 3 which is adapted to fit the reduced, screw-threaded, outer end portipn4 of theaxle. A jam nut or other suitab e locking device 5 may also be provided for. the bearing ring 2.

Surrounding and spaced from the axle portion-lis a hub sleeve or bushing 6. The hub sleeve is provided with an enlarged l circular end portion or bearing iing 7 which is adapted to coperatewith the inner bearing rmg 2. Interposed between the two bearmgprings 2 and Klare a serles ofrcllers 8. The end portions'of these ifollers are.l

lare of smaller dimensions so as to be loosely and freely mounted therein. By the arrangement of the series of perforations 13 the body member of the spacing frame constitutes in effect a pair of spacing rings or annular portions 14 which are connected by cross members 15.

The thickness of the body member of the spacing frame is slightly greater than the diameter of the roller spindles 12, and the body member is oppositely notched at each end of the several elongated perforations or slots 13 centrally thereof as at 16 so as to loosely receive said roller spindles 12. As shown in Figs. 1 to 4, inclusive, narrow rings or strips 17 are riveted or otherwise secured on the inner side of the marginal ring portions 14 so as to overlie the notches 16. On the outer side of one of the margin al ring portions 14 is secured a ring or strip 18 which alsooverlies the notches 16 opposite to its companion ring or strip 17. O n the outer side of the other marginal ring portion 14 are preferably hingedly mounted two semicircular bails or strips 19 which' are adapted to be swung off of said marginal ring portion 14 when it is desired to place the rollers on the cage frame or remove them therefrom. The arrangement ofthe circular strips or rings overlying the notches 16 at the ends of the slots or perforations 13 provides retaining pockets or seats for lthe end spindles 12 of the rollers. By providing the two movable semicirc-ular bails or strips 19i the rollers may be easily and readily placed on the-spacing frame or cage. That is, the rollers may be mounted on one-half y' ofthe cage at a time, thereby obviating the necessity and overcoming the hiculty of holding the entire series of rollers in place :i'mtil the movable securing ring orl bails are "'elbsed on the margin ring portion.

said uncovered notches.

In placing the rollers on the cage, it is only necessary to swing the bail ott' of the marginal ring portion 14 as shown iu Fig. `5, and holding the cage with the uncovered notches uppermost, the rollers may be placed by inserting one of their end spindles into the companion covered notches and then dropping their opposite end spindles into rl`he bail or movable securing member 19 may then be closed. Obviously, the rollers will be as easily and readily removed.

In Fig. 5, the bails 19a are placed on the inner side of the marginal ring portion 14. In other respects this modification is similar to that hereinbei'ore described.

In Figs. 6 and 7 a blank 20 for a further fniodication of the spacing frame or cage is shown. In this case the body portion is formed from a perforated strip. That is, the strip may be punched or otherwise perforated and then formed into a ring and tempered if so desired.

Obviously, the device may be further' modified Without departing from my invention, and, therefore, I do not wish to be limited to the exact constructions and arrangements herein shown.

1What I claim as my invention and desire to secure by Lett-ers Patent is:

1'. roller bearing comprising a series of spaced rollers having axial end spindles, and a spacing frame for said rollers comprising a pair of rigidly connected annular portions, one of said annular portions having a series of longitudinally inwardly opening recesses therein', and the other of said annular portions having a series of longitudinally inwardly and radially opening recesses therein Which are arranged in coInpanion relation to said Erst-mentioned series of recesses, and removable means for covering the radial opening of said last mentioned recesses.

2. A roller bearing comprising a series of spaced rollers having axial end spindles, and a spacing frame for said rollers comprising a pair of rigidly connected annular portions, one of said annular portions having a'series of longitudinally inwardly opening recesses therein, and the other of said annular portions having a seriesof longitudinally inwardly and radially opening recesses therein which are arranged in companion relation to said first-mentioned series of recesses, and removable means for covering the radial opening of said last mentioned recesses, said means comprising two oppositcly disposed semi-circular bails which are hingedly connected to the ring.

3. In a roller bearing, a spacing cage comprising a pair of rigidly connected annular portions, one of said annular portions having a series of longitudinally inwardly opening recesses therein, and the other of said annular portions having a series of inwardly and radially opening recesses therein which are arranged in companion relation to said first mentioned series of recesses and removable means for covering the radial opening I of said last mentioned series of recesses.

4. In a roller bearing, a. spacing cage colnprising a pair of rigidly connected annular portions', one of said annular portions having a series of longitudinally inwardly opening recessestherein, and the other of said annular portions having a series of inwardly and radially opening recesses therein 'which are arran ed in companion relation to said first-mentioned series of recesses, and removable means for covering the radial openin of said last mentioned series of recesses, sai

means com rising two semicircular hails which are hingedly attached to the ring.
